I've found the following statement in a blog post (http://www.tek.com/blog/how-source-meas ... ry-and-oth), written by Bill Pelster, the Director of Quality for the Keithley product line of Tektronix, Inc.
If there are indeed some open source scripts for the 2450 (and I would trust the Director of Quality that there indeed are), could someone from Keithley please provide the public with a download link? I couldn't find anything similar at the user support/downloads section of the Keithley's website.Keithley has developed open source code scripts (they are similar to the Lua programming language) that can perform:
Linear Sweep Voltammetry
Open Circuit Potential
Potential Pulse and Square Wave Voltammetry
Current Pulse and Square Wave
Chronoamperometry (current versus time at a controlled potential)
Chronopotentiometry (voltage versus time at a controlled current)
